HELP ASAP

Mathematics
1 answer:
Mamont248 [21]3 years ago
3 0

Answer:

m = 0

Step-by-step explanation:

distribute

7 + 35m + 2m = 7 +2m

add 35m + 2m

7 + 37m = 7 + 2m

subtract 2 from 37m

7 + 35m = 7

subtract 7 from 7

35m = 0

0 ÷ 35 = 0

so technically the answer is 0

I'm not 100% sure but I do believe this is right

The variable z is directly proportional to x. When x is 11, z has the value 44. What is the value of z when x = 21?
dimulka [17.4K]

Directly proportional, both increase/decrease, Multiple k(constant you needed to solve for)..

Inversely --one increases as the other decreases, increase the denominator & fraction gets smaller.... So

Problem:

Dirextly to X (× by X)

Inversely to Y, (÷ by Y)

Z= k X/Y

Solve, working backwards: Z =5 becomes

5 = k (X) ÷ (Y). And

X=15 and Y =9 becomes

5= k(15)/(9). Undo ÷9, ×9 both sides

45= k(15). Now undo ×15 by ÷15 both sides

45/15 = 3. So k=3, (also called your constant of variation)....and your Equation/Proportion becomes...

Z = 3X/Y

Use the new #s.... X=23, Y=14

Z= 3×23÷14 = 69/14. If they want spirochete answer divide and round to corresponding # if decimals

Can some help I’m suffering with this question
ziro4ka [17]

Answer:

38 quarters

Step-by-step explanation:

0.25 x 63 = 15.75

0.05 x 63 = 3.15

----------------------------

0.25 x 50 = 12.50

                    +         = $13.15

0.05 x 13 = 0.65

----------------------------

0.25 x 25 = 6.25

                   +        = $8.15

0.05 x 38 = 1.90

----------------------------

0.25 x 30 = 7.50

                   +         = $9.15

0.05 x 33 = 1.65

--------------------------

0.25 x 35 = 8.75

                   +        = $10.15

0.05 x 28 = 1.40

-------------------------

0.25 x 38 = 9.50

                   +        = $10.75

0.05 x 25 = 1.25

------------------------------

I hope this helps!
